5 Claims.

This invention relates to improvements in dyeing machines formarquisettes and method of dyeing.

its object is to provide a simple apparatus for applying color to theclip spots or projections of textiles of this type without coloring thebody portion of the cloth.

Another object is to so construct the machine that it may be usedindependently for dyeing the bodyof the cloth.

It has been necessary heretofore, in order to get clip spots of adifferent color or shade than that of the body, to use dyed yarn forweaving the clip spots and to cut this yarn at the spots with aresultant loss of yarn.

Another object of my invention is to do away with this loss.

Another objectis to provide an improved meth- 0d of dyeing such fabrics.

These and other objects will appear in the following specification inwhich I will describe the invention, the novel features of which will beset forth in appended claims.

Referring to the drawing,

Fig. 1 is a side elevation of a machine which is made according to andembodies my invention;

Fig. 2 is an end View of the machine shown.

in Fig, l;

Fig. 3 is a side elevation on a larger scale of some of the parts oi.the machine shown in the preceding figures, illustrating its operation;and

Fig. 4 is a view similar to that shown in Fig.

r it, operated in the usual manner by the shaft II by mechanismindicated generally by the reference numeral l1. 6

29 and 2| designate guide rollers near the upper parts of thesideframes, parallel with the engraved roll 12, above and laterally spacedtherefrom. 22 and 23 are similar rollers supported in the side frames,also laterally spaced from the engraved roll at such an elevation as tosurface of the other, such as the roller 22 at or slightly below theupper surface of the engraved roll.

Y 30 is a transverse blade above the engraved roll l2, movablevertically between stationary 5 guides, such as 3|, 32, affixed to theside frames, (Fig. 1). This blade has a curved side 33 and,

. as shown, a straight side 34 in a plane through the axis of roll l2.Near the ends of the blade are threaded holes in engagement with whichare adjusting screws 35, 36, aflixed to the upper ends of which are handwheels 31, 38. Collars, such as 39. (Fig. 1) are aflixed to the screws35, 36 to hold them against longitudinal movement. By this arrangementthe blade 30 may be moved vertically and its position relative to theroll l2 adjusted.

40 designates a fabric provided with clip spots ll, This is run from acloth frame, (not shown), where the fabric is sprayed with finishingmaterial and dried, over guide roller 20 with the clip spots against theroller, down to and under blade 30 and thence up to and over guideroller 2|. It

approaches the curved side 33 of blade 33 in a tangential relation andas it bends around the edge formed by the intersection of the sides 33,34, the clip spots are opened. This edge of the blade is so adjusted asto bring the opened clip spots, but not the body of the cloth, intocontact with the engraved surface l3 of roll l2, whereby they absorb thedye stuff in the engraved portions of the roll. The amount of the dyestuff dispensed by the roll depends upon the depth of itsengraving,-rolls with deep-engravings being used with large clip spots.

The curved side of blade 30 overcomes the tendency to pick up lint,whichthe scraping effect of a flat sided blade would have.

This machine may be used to dye the body of the fabric, as shown in Fig.4. In this case the blade 30 is not used and the fabric is led, theother side up, over the guide roller 22, the en-. 'graved roll l2 andunder the guide roller 23. In this case the amount of dye applied mustbe enough to permeate the ground of the fabric, but not suilicient torun through into the clip spots. 1

Modifications may be made within the spirit and scope of this inventionand I intend no limitations other than those imposed by the appendedclaims.

What I claim is:

1. A dyeing machine comprising a rotatable cylindrical roll, a dye panunder said roll, means for passing a fabric having a body and fibers forpassing a fabric having a body and fibers projecting from a side of saidbody across said roll with the body and the projecting fibers in contactwith the roll, said means including a transverse blade over and spacedfrom above the blade and laterally spaced therefrom, the approach sideof said blade being. convexly curved, said rollers being arranged toguide the fabric to and from the blade at acute an les to a planethrough the blade and through the axis of the roll.

3. A dyeing machine comprising a rotatable cylindrical roll, a dye panunder said roll, means for passing a fabric having a body and fibersprojecting from a side of said body across said roll with the body outof contact with the .roll and the projecting fibers in contact with theroll, said means including a transverse blade over and spaced from theroll, means for leading the fabric to and from the blade at acute anglesto a plane out of contact with the roll the roll, and guide rollers.

through the blade and through the axis of the roll, and means foradjusting the blade vertically.

4. A dyeing machine comprising a rotatable cylindrical roll, a dye panunder said roll, means for passing a fabric having a body and fibersprojecting from a side of said body across said roll with the body outof contact with the roll and the projecting fibers in contact with theroll, said means including a transverse blade over and spaced from theroll, guide rollers above the blade and laterally spaced therefrom, theapproach side of said blade being convexly curved, said rollers beingarranged to guide the fabric to and from the blade at acute angles to aplane through the blade and through the axis of the roll, and means foradjusting the blade vertically.

5'. The herein described method of dyeing clip spots which comprisesapplying a film of liquid dyeingmaterial to a feeding surface, moving afabric having a body and clip sp ts projecting from one side of its bodyalong a path of travel toward said surface and away from said surface atdiverging angles transverse to said surface,

the fabric being fed with the clip spots disposed toward said movingsurface, whereby the fabric is bent transversely on a line near butspaced from said surface and its clip spots are opened against saidsurface.
